LEED in Sofia

The Embassy in Sofia was the first to be awarded LEED (Leadership in Energy and Environmental Design) when it was constructed. The features include a pulse-powered water treatment system, water saving fixtures and a drip irrigation system to reduce water consumption. More than 95% of the light bulbs is energy saving and light sensors ensure that lights are turned off when areas are not in use or when there is sufficient daylight. Timers are similarly used to shut down systems after hours. Solar water heaters and a heat exchange connected to the hot water system are utilized to reduce energy use. In addition, greater insulation has been obtained through the thermal properties of the external materials. Outside containers also promote recycling by employees after hours.
